Signal - Private Messenger

By Open Whisper Systems

Description

Privacy is possible. Signal makes it easy.

Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real-time with all of your friends at once, and share media and other files with complete privacy. The server never has access to any of your communication and never stores any of your data.

• Open Source - Signal is Free and Open Source, enabling anyone to verify its security by auditing the code. Signal is the only private messenger that uses open source and peer-reviewed cryptographic protocols to keep your messages safe.

• Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.

• Group Chat - Signal allows you to create encrypted groups so that you can have private conversations with all of your friends at once. Not only are the messages encrypted, but the Signal server never has access to any group information like the membership list, group title, or group icon.

• Fast - The Signal protocol is designed to operate in the most constrained environment possible. Messages are delivered quickly and reliably.

• Speak Freely - Make crystal-clear voice and video calls to people who live across town, or across the ocean, with no long-distance charges.

What's New in Version 2.19.2

• Faster message processing and more efficient network usage.• Signal has been fully updated to support the iPhone X.• We revamped our layout code to improve performance and flexibility. Everything should feel smoother and more refined.• Additional messages now appear automatically when you scroll to the top of a conversation. You won't need to tap on the “Load Earlier Messages” link ever again (and you also can't because it's gone).• “Jumbomoji” have arrived. Emoji characters are visibly larger in messages that do not contain any other text. Your thumbs-up sign has never looked better.• Although we can't fix the weak WiFi in the corner of the coffee shop, we made it a whole lot easier to spot failed messages and to send them again.• A “Tap For More” option makes navigating extraordinarily long messages much more pleasant.• Quickly send photos, files, or GIFs using a newly simplified interface. Attachment previews are displayed directly in the message bar instead of on a separate confirmation screen.• Users with external keyboards can send messages using Shift+Return or Cmd+Return. Reaching up and tapping the send icon remains an option for anyone who reminisces about the past.• The list of supported languages has expanded to include Burmese, Hebrew, and Persian. We sincerely appreciate the volunteer translators whose efforts made this possible.

We said farewell to the following bugs:

• Under rare circumstances, message drafts could mysteriously vanish.• Adjacent message statuses behaved incorrectly after deleting a message.• Users who were simultaneously running the desktop version of Signal could receive redundant notifications.• Edit items might be missing from the long-press menu.• The input toolbar could remain raised even when no keyboard was visible.• Recently sent messages sometimes reappeared after being deleted.• Some users on iOS 11 were unable to save images to their Camera Roll.

Signal is made for you. Thank you for your feedback and support.

It was great until the most recent update

by

I have been using Signal and have enjoyed the privacy it offers, and also was really happy to see the GIFs update. When I installed the most recent update though, I’m suddenly having problems pressing the back button on the top left of the screen when I’m in a chat window and want to go to the home screen with all my conversations. For some reason it takes a lot of taps to go back and the app doesn’t pick up that I want to do that. Please fix this!!

Best Privacy Communication App

Signal (company) does not keep your contacts, just a cryptographically representation.

It's completely open source so we can assume it doesn't have backdoors.

Signal does not keep IP logs to share. If you're afraid, use it with an VPN.

Having usernames would be great but they chose phone numbers because it's simpler. If you want to hide/protect your phone number, get a burner phone (or an app) just to receive the SMS confirmation to register.

What I love about Signal is that the app is less prone to errors like saving chats in the cloud unencrypted (WhatsApp) or not having e2e encrypted chats by default (Telegram).

Wish they had the option to delete messages on both sides and (optional) usernames implementation. Both features Telegram have.

Still missing some features

Great app overall. Makes improvements with every update but still missing some basic features like batch adding pictures and scrolling thru media. Gets very laggy when there are other apps open.
